Most engineers can write code. Fewer can take a vague product idea, architect it properly, and ship something that holds up in production six months later without it becoming someone else's problem to maintain. That's the work I do. I'm Vikram, a Senior AI and Full Stack Engineer with 6+ years of experience, $70K+ earned, and 25+ projects delivered on Upwork. I work with startups and product teams who are building things that actually need to work: AI-powered systems, scalable SaaS backends, and full stack platforms that grow with the business. If you have ever been handed code that "technically works" but nobody can explain, or an AI demo that never made it to production, you'll know exactly why architecture and delivery discipline matter. That's where I come in.

I'm an AI agent developer and backend architect with 10+ years building production AI systems: autonomous agents, RAG pipelines, and automation that hold up under real users and real load. I've scaled platforms to 50M+ users and shipped AI for clients across the US, UK, and Australia. IIT Kanpur alumnus. I bring both the systems depth to make AI reliable and the product sense to make it useful. What I build: 1. AI agents and agent infrastructure. Autonomous agents, MCP servers, tool use, function calling, and multi-agent orchestration that run real workflows across ops, sales, and support. I also build the harness around them, state, retries, guardrails, and observability, so they hold up in production, not just in demos. 2. RAG pipelines that survive real load. Query embedding, parallel vector search, context assembly, and streaming LLM synthesis, with ETL ingestion, chunking, dedup, and PII guardrails built in. 3. Scalable, multi-tenant backend architecture. Node.js, TypeScript, NestJS, and Python microservices with multi-tenancy, governance, and security designed in from the start, over polyglot data layers: Postgres, MySQL, MongoDB, Redis, Elasticsearch, Neo4j, ClickHouse. 4. Workflow automation and integrations. End-to-end automations with n8n, Make, Zapier, and Temporal, wired into the tools teams already use: Slack, Notion, WhatsApp, ClickUp, Telegram, and more. Selected work: - Scaled a creator-economy platform to 50M+ users on AWS EKS and Cloudflare Workers, including payments infra with Stripe Connect, Apple IAP, and Google Play Billing. - Built AI agents and MCP servers for an AI-native business platform handling finance, sales, and support workflows. - Re-architected an autonomous AI worker platform for multi-tenancy, scalability, governance, and security. - Designed a conversational RAG copilot on PostgreSQL + pgvector for project management and admin tasks via natural language. - Integrated Facebook, Google, Instagram, and TikTok ad APIs across 800+ store locations for local inventory ads and ROI tracking. Core stack: Models and frameworks: GPT-4o, Claude, Gemini, LangChain, LlamaIndex, AutoGen, CrewAI, LangGraph, LangSmith, Semantic Kernel, DSPy. Agent infrastructure: MCP servers, function calling, tool use, multi-agent orchestration, OpenClaw, Hermes, LangServe, Modal, Replicate. Vectors and memory: Pinecone, pgvector, Weaviate, Chroma, Redis. ML and DL: TensorFlow, PyTorch, Hugging Face, Scikit-learn. Backend: Node.js, TypeScript, NestJS, Python, FastAPI, GraphQL, WebSockets, WebRTC, RabbitMQ. Data: Postgres, MySQL, MongoDB, Redis, Elasticsearch, Neo4j, ClickHouse, Firebase. Integrations: Slack, Notion, WhatsApp, ClickUp, Telegram, Twilio, Akamai, Rosette, Facebook Graph, Stripe, and marketing APIs across Facebook, Google, TikTok, Twitter, and Dropbox. Cloud: AWS (Lambda, RDS, SQS, OpenSearch, Neptune, S3, ElastiCache, Comprehend, Rekognition), GCP (Firestore, Cloud Functions). If you need someone who can take an AI idea from prototype to a system that survives real users and real load, let's talk. I reply fast and ship faster.

Your support team answers the same questions every day, and a generic bot only makes it worse. I fix that as an AI Chatbot Developer, AI Engineer, and System Architect: a chatbot built on your real data with Agentic RAG and AI LLM orchestration, engineered in Python, gives accurate, source-cited answers 24/7, with no human intervention. That is the difference between a real chatbot and a demo, and it is what an AI Engineer designs every Python system to deliver. Top Rated AI Chatbot Developer and AI Engineer on Upwork · 50+ AI Chatbot systems in Python · 10+ years software engineering · 100% Job Success · $100K+ earned across healthcare, finance, SaaS, and real estate. The principle behind every build: a chatbot that isn't grounded in your knowledge base is just a science project. So as an AI Engineer and System Architect, I ground each chatbot in your actual documents and databases with Python RAG systems, and I tune the Agentic RAG layer in Python until the AI LLM answers from your data, not from guesswork. Deep RAG tuning and AI LLM refinement is where an AI Engineer earns the result. What I build: Agentic RAG chatbots: context-aware chatbot answers drawn from your own documents over RAG pipelines with Pinecone, Qdrant, or Chroma, on Claude, GPT-4, or Llama 3, wired together in Python. Sources cited, no hallucinations, every AI LLM answer grounded in your data by an AI Engineer using RAG architecture. AI LLM-powered RAG workflows: Python with LangChain and LlamaIndex that read documents, extract insights, and automate multi-step work end to end with RAG retrieval, AI LLM retries and exception handling in Python. Engineered by an AI Engineer with RAG expertise and architected by a System Architect, with the chatbot layer sitting on a scalable Python RAG core. GenAI & NLP apps: a text, voice, and image chatbot with full conversation state, RAG grounding, and multi-platform deployment, shipped end to end in Python by a System Architect. Healthcare & telehealth: HIPAA-compliant Agentic RAG chatbot pipelines with strict data grounding and audit trails, built in Python by an AI Engineer and System Architect with real healthcare experience and RAG compliance. Rapid MVPs: a working RAG-powered chatbot in weeks, not months, delivered as clean, documented Python your team can own as a maintainable Python asset. That is how an AI Engineer builds a Python chatbot with RAG to hand off. Results: support costs cut 35-55% with an Agentic RAG chatbot · 100+ hours/month recovered through AI LLM automation and RAG efficiency in Python · up to 60% revenue lift from smarter chatbot engagement powered by RAG. These are the numbers an AI Engineer and System Architect are hired to move. How I work: Discovery, then Agentic RAG and AI LLM architecture in Python, then a fast MVP, then scaling for accuracy, speed, and multi-platform deployment. Because I work across every major AI LLM and open-source AI LLM provider through Python RAG systems, I'll tell you honestly whether Claude, GPT-4, or open-source fits your accuracy, cost, and privacy needs before you commit. What separates a real System Architect from an API-wrapper is designing each RAG chatbot for real data, real edge cases, and real production load in Python, the standard an AI Engineer is held to across every AI LLM and RAG implementation I deploy. Scalability and infrastructure: a chatbot that's fast in a demo and slow under load is a failure, so as a System Architect I design the data flow, caching, and failover in Python that keep your RAG chatbot fast at scale. An AI Engineer plans the Python RAG system before a line of code ships, and a System Architect owns the trade-offs between cost, latency, and accuracy. Tech stack: Python · Claude · GPT-4 · Llama 3 · LangChain · LlamaIndex · AutoGPT · Autogen · Pinecone · Qdrant · Chroma · Node.js · Django · TensorFlow · Docker · AWS · Azure, the Python toolkit an AI Engineer ships with. Want a RAG chatbot or Python product that's measurable, not a science project? Message an AI Engineer and System Architect who has shipped 50+ Python chatbot systems with RAG. As your dedicated AI Chatbot Developer, AI Engineer, and System Architect, I offer a free 30-minute consultation to map your Agentic RAG and AI LLM roadmap in Python before you spend a dollar. Bring your use case and a System Architect who grounds every chatbot in real data and clean Python will scope it properly. That is the commitment a System Architect stands behind, and the reason a grounded RAG chatbot earns the contract.
